CATCH-BASIN FOR SEW ERS.

SPECIFICATION forming part of Letters Patent No. 601,794, dated April 5, 1898. Application led Bebruary 17, 1837. Serial No. 623 ,774. (No model.)

To all whom, t may concern:

Be it known that I, JOSEPH W. HERsHBER- GER, a citizen of the United States, residing at Plymouth, in the county of 'Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Catch-Basins for Sewers, of which the following is a speciflcation, reference beinghad therein to the accompanying drawings.

My invention relates tovcatch-basins for sewers in which water from the street, carrying with it dirt and trash, will flow into the basin and when full the water will overflow into the sewer, while the dirt and trash will settle in the basin, from which it can be subsequently removed. v

The object of the invention is to provide an improved catch-basin vwhich shall possess superior advantages with respect to efficiency in use; and it consists in the novel construction and combination' of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is alongitudinal sectional view of a catch-basin constructed in accordance with my invention. Fig. 2 is a plan view showing one half with the cover removed land the other half with the upper section of the casting removed. Fig. 3 is a View partly in elevation and partly in section.

In the said drawings the reference-numeral 1 designates the basin, made of brick or stone work and preferably cylindrical in form. Seated upon the top of this basin is a twopart semicylindrical casting comprising an upper section 2 and a lower section 3. The lower section is provided with a flange 4, with which the lower edge of the upper section engages. f The said upper section is provided with a rectangular cover 5, having an angular locking-bolt 6, which engages with an angular lug 7, formed in the inner side of said section, by which the cover is held in place. At the rear, sides, and front corners the said sections are formed with apertured lugsv 8, through which pass screw-bolts 9, by which said sections are .connected with each other. By means of these screw-bolts, also, the said upper section is extended upwardly into a rectangular form and may be adj usted to conform to the grade of the street. 'In the front side of the upper section is an inlet-opening with which communicates the upper flaringv section 10 of an inlet tube or pipe 12. The lower section 13 of this tube or pipe is made fiaring or conical and terminates in the upper portion or end of the basin and is central therewith.

The numeral 14 designates a gutter at opposite sides of the lower section 3 and extending from the inlet-opening nearly around said casing and having an inclined bottom 15. This gutter communicates with an outlet-pipe 16, connected with a trap 17, which in turn is connected with a sewer.

The numeral 18 designates a movable grating consisting of a number of curved bars 19, which pass through brackets secured. to

the lower casting 3, and their upper ends eX tend up over the gutter to prevent trash from` entering the same. This grating may be turned back out of the way when the basin is being cleaned.

The numeral 2O designates openings in the gutter to allow the water that may stand in the basin to drain out to the level of the opening, so as to reduce the possibility of freezing in cold weather.

The operation is as follows: Water from the street will enter theinlet-opening and from thence will be conducted by the upper section of the inlet-tube to the conical lower section, from whence it will fall centrally in described, the combination with the two-part v or sectional casting formed with apertured gutter, and the outlet-pipe 16, substantially lugs, S, the upper section having an inlet as described.
